To (ir/ZZ whom, zit may concern.'

Be it known that I, DENNIS T. IGOU, a citizen of the UnitedStates, residing at Springfield, in the county of Clark and State of 5 Ohio, have invented certain new and useful Improvements in Machines for Forming and- Wrapping Confections and other Articles, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to machines for forming andwrapping confections and other articles, and particularly to that part of such a machine as constitutes the wrapping mechanism; and the special object of my invention as regards this wrapping mechanism is to aord speed in wrapping the article as well as accuracy, so that while the wrapping function shall be perfectly done the output of the machine will also be largely increased. To this end, the confections, with their wrappers folded around them, are directed alternately in two different paths, and duplicate groups of handlingr and twisting mechanism are employed, so that one set of twisting mechanism will be operating to twist. the wrapper of a confection while the other set of twisting mechanism is returning to its original position to operate on the next confection. In this way, the machine is always twisting a confection, instead of being idle during onehalf of the time, two wrapped confections are delivered for each complete cycle of the wrapping mechanism, instead of one, and the output of the machine is doubled.

vIn the accompanying drawings forming a part of this s eclfication, on which like reference numera s indicate corresponding parts,

'Fig 12 is an enlarged fare View of one ol' thc trated, particularly in Figs. 1, 2, 3 and y-l, this machine generally, while in the remaining figures I have illustrated more particularly those features which constitute the subject matter of this present application. The parts of the drawings not spccilically described and not indicated by the reference numerals do not enter into the present invention, and hence the specific description of the parts designated by the numerals arc those parts which do constitute the present invention, or are incidental thereto, in that preferred lembodiment thereof which is so illustrated.

The frame 1 has two parallel longitudinal members 203, having a lower set of guideways 204, in .which travels a slidel 205, and an upper pair of guideways 206, in cach of which travels a slide 207. These slides 205 and 20T are so actuated as to move simultaneously in opposite directions, their movements being preferably effected in the manner illustrated. T he crank shaft 62 is provided with a crank pin 208 on the rear face of thc gear 64, to which crank pin there is connected one end of a connecting rod 200, Ithe other end of which is connected to th(` slide 20.5, as indicated at 210. The crank shaft 6G is provided at each end with a crank arm 211, to thecrank pin 212 of which there is pivotczi one end of a connecting rod 213. Ther connecting rods 213 have their other ends pivmove in unison, and constitute practically a i: single slide, moving in a direction opposite to 'the slide 205.

About midway of their length the longltuuinal members 203 are connected by a brldge or support composed of a lower plate 215, supported on abutments216, and

an upper plate 217, supported above the plate 215 by interposed spacing pieces 218, so as to leave between the plates a space 219, open at each end toward the ends of the machine. On the plate 217 vthere is mounted a standard 220, which extends upward above the same and serves as a guide for a verticallyacting plunger 221. To this end, the upper end of the standard 220 is provided with arallel fianges 222, supporting pairs of guiding rollers 223, between which the plunger 221 fit-s and is guided. Movement is impartedto the plunger 221 by means of a cam plate 224, supported by arms 225 from one of the slides '207 and passing through a slot 226 in the plunger 221. The cam plate 224 is provided with a cam slot 227, having a straight or horizontal central portion 228, and downwardly inclined end portions 229 and 230. The plunger 221 is provided with a roller 231 which fits the cam slot 227, and by its engagement therewith serves to raise and lower the plunger at the proper times. The plunger is'provided with a detachable foot, which serves, among other purposes, as a stop to arrest each confection as it is delivered from the conveyer belt 104, as illustrated more particularly in Fig. 6. To this end the plunger foot, indicated as a whole by the reference numeral 232, is provided with a downwardly projecting lip or flange 233 at the end thereof farthest from the conveyer 104. The confection, as it is delivered to the wrapping mechanism, is arrested by contact withl the stop 233, and comes to rest immediately underneath the plunger foot 232, as shown in Fig. 6. As already stated, the plunger foot is removable to give access to the confection, wrapper, and underlying ,parts when necessary, and to this end the plunger is provided at its lower end with grooves 234 on each side thereof, the plunger foot being provided with corresponding grooves in its under side to receive the lower end of the plunger, and ribs or projections 235 to fit the grooves 234. The foot is provided on its rear side with a handle or finger grasp 236, by means of which it can be readily slipped on ando the plunger from the rear side thereof, and, in order to lock the foot in position on the plunger, said foot is provided with an upward extension 237, which engages under a plate 238, mounted to slide vertically on the rear edge of the plunger, being provided for this purpose with slots. 239, through which pass screws 240 threaded into the plunger. By sliding the plate 238 upward, the locking projection 237 is disengaged, and the'plunger foot may be withdrawn. This co .istruction is shown in detail in Figs. 6 and 8.

The plunger is provided at its lower end with folding plates 241, located one on each side-thereof and extending below the lower face of the plunger foot to a\ ,listance somewhat greater than the height or thickness of the confection. These plates are separated from each other by a distance which is slightly in excess of the width of the confections, as shown in Fig. 8. The plates 241 are notched at their lower edges, as indicated at 241, to receive the gripping fingersl 279, hereinafter referred to,'when said plates are depressed. It will be understood that the severed sheet of paper which is to constitute the wrapper is fed forward by the gripping fingers into the position shown in Fig. 6, the wrapper being indicated. by the reference numeral 242 and the confection by the reference numeral 243. The sheet is supportedv along its lateral margins by the guides 181 and 182, between which it rests, and it will be noted that, for convenience of construction, the place of one of the lower guides 182 is occupied and its function accomplished by the marginal portion of the base 244 of the standard 220. The upper bridge plate 217 is provided with a .slot 245, having a length at least equal to the length of the wrapper 242, and a widthv slightly greater than the width of the plunger between the outside surfaces i of the folding plates 241, being about equal to the distance separating the two pairs of guides 181 and 182 on the opposite sides o`f the plunger. guidesv there is located a support 246, mounted on the upper end of a stem or shank 247, which moves verl ically in alinement with the plunger 221. This stern is guided at its lower end by means of an apertured lug 248 on a casting 249, secured to the main frame 1. About midway of `its height there is secured to the stem 247 a plate 250, which slides in guideways 251, mounted on the up- Vper end of an upright 252, secured at its lower end to the casting 249 and extending upward through a slot 253 .in the slide 205. This stem and supporting plate are pressed upward by-means of a spring 254, coiled. around a stud shaft 255, projecting from the casting 249. On this stud shaft there is In the space between saidV loosely mounted an arm 256, which is acted on by the spring 254, and which has pivoted to its free upper end one end of a link 2557. The other end of the link 257 is pivoted to a clip 258, secured to the stem 247i The lower end of the stem 247, below the lug 248, is provided with nuts 259 andv cushioning washers 260, by means of which the limit of v upward motion of the support 246 may be adjusted and through which any shock or jar is avoided when the said limit is reached.

As shown in Figs. 5 and 6, the support 246 is preferably somewhat longer than the confection, while its width, at least at its central portion, is made somewhat less than the lwidth of the confection, it being preferably cut away one each side, Vas indicated at 261. The lower bridge plate 215 is provided with an aperture 262, to receive the support 246 when it is depressed in the manner hereinafter described.

The vertical movementsof the support 246 are controlled in part by the movements of the plunger 221, and in part by a cam plate 263, secured on the slide 205. The cam plate has a large opening 264 formed through it at each'end, while its central portion is o ecupied by a body 265, shown in dotted lines in F ig. 8, which body cuts off any connection between the two open end portions 264 of the cam slot at the top thereof, leavin-g a passage 266 atthe lower portion thereof. The ends of the body 265 are rounded oil', as indicated at 267. (.)n the outer face of the body 265 there is mounted a plate 268, which extends beyond the body in each direction, and is provided at each end with a bearing sleeve I 269, in which is mounted the shaft or journal l27() of a switch 271, lying within the cam -groove at each end. of the passage 266.

These switches are forced normally down ward into the position shown by means of springs 272, which bear upon pins 273, w hieh project from the shafts or journalsl 270 through slots 274 in the bearing sleeves 269. The slide 250 is provided with a roller 250 which travels in the slot of the cam plate 263.

)n the under side of the lower bridgeplate 215 there is secured a bracket 275, from which extend downward guideways 276, in which there is mounted to slide vertically a plate or slide 277. This plate has pivoted to its front face, at 278, the lower ends of two uplwardly extending gripping fingers 279, w ich extend up through the slot 262 in the lower bridge plate 215, projecting normally into the s ace 219. These fingers are held normally 1n the position shown by a spring 280, coiled around the projecting end of a rod 281 which connects the gripping fingers, the tension of the spring being adjusted by a thumb nut 282. The position of the slide 27 7 and gripping fingers 279 is controlled by a cam plate 283 secured to the slide 205 and having a cam groove 284, in which engages a roller 285, mounted on a bearing stud 286, projecting from the rear of the slide 277. The cam plate 283 also serves to transmit motion from the slide 205 to a tucker 287, mounted to slide in the space 219 in a direction lengthwise of the machine and at right angles to the direction in which the confections and wrappers arefed to the wrapping mecl'ianism. To this end ,thereis secured to the upper edge of the cani plate 283 a plate or standard 288, which extends up through a slot 289 in the lower bridge plate 215 and is securedto the under side of the tucker 287,

so as to cause this latter to move in unison with the slide 205. The lower bridge plate 215 is provided on its upper side with a way 290, u on which the tucker fits, as shown in dette lines in Fig. 6, so as to be properly guided in its movements. provided on its upper surface with folding anges 291, which project beyond the body of the tucker on both sides in the direction of its travel. Thesefianges, and the body of the tucker, are slotted vertically along their opposite margins, as shown at 293, to accommodate the rake teeth hereinafter referred to.

The tucker is The wra ping mechanism, so far as it has now been t escribed, serves to fold the wrapper around the .confection and present the package in this condition to the twisters by which the ends of the wrapper are twisted. l will therefore describe the operation of this portion of the mechanism before proceeding to describe the twisters and theirv mode oll operation. l

Assuming that the parts are in the position shown in Figs. 5, 6 and 8, the wrapper has been delivered between the guides 181 and 182, resting on the guides 182 and support 246, and a confection has just been delivered, resting 011 the wrapper and supported by the support 246. The slides 205 and 207 are moving in opposite directions., as indicated by the arrows in Fig. 8, and the roller 23.1 of the plunger 221 is engaged by the inclined portion 23() of the cam slot 227 inthe cam bar 224 at the top of the machine, which is actuated by the slide 207. 'lhe .plunger 221 thereupon moves downward, and the folding plates 241 carried thereby pass down on each side of the confection until they come into contact with the wrapper as it rests upon th(` support 246. Further downward movement of the plunger 221 depresses the support 246 against the action of the spring 254, at the same time firmly gripping the wrapper against the su) )ort along the 'lirst lines of fold, which folds are formed by the lower guides the wra per is carried down between them, and a so by the side walls oi' 'the slot 245 in the upper bridge plate 217. 'lhis downward movement continues until the u per surface of the support 246 is level with or below the upper surface of the lower bridge plate 215, whereupon it ceases. During the latter portion of the downward movement of the parts, the confection is gripped through its wrapper.between the gripping fingers 27 9, the cut-away portions 261 at the sides of the support permitting the fingers to grip the confection, which is held between them by the tension of the spring 280. The cam plate 263 does not interfere with this downward movement of the support 246 under the iniiuence of the plunger 221, since the roller 250a is engaged in. the open end portion 264 of the cani slot iii said late and is there# fore free to move downwar The cam plate 283 holds the gripping fingers 279 against vertical movement by reason of the engagement of the roller 285 ofthe slide 277 in the straight or horizontal end portion of the cam lslot 284.

Then the slides reverse the direction of their travel, the plunger 221 movesupward, but the confection is prevented from being carried upward by said plunger, in case it should happen to adhere to the same, by reason of its heilig gripped between the fingers 279. The support 246 is prevented from following the plunger 221 upward by reason of the fact that the point of connection of the link 257 with the stem 247 of said support passes below tlic point of connection of said link with the spring-actuated arm 256, and when the parts are in this position, it is obvious that the spring 254 will act to force the said stem and support downward andhold them in such depressed position. 'As the cam plate 263 advances, the roller 250a passes under the switch 271,.which yields upward to permit it to pass, and into the 'portion 266 of the cam slot, which serves to act as an additional safeguard for preventing upward movement of the support during this portion of the operation of the machine. The tucker 287 is now approaching the confection which lies in its path, but before the tucker reaches it, the gripping ngers 279 are drawn downward out of its path, at the same time releasing the confection, by reason of the engage-V ment of the roller 285 with the downwardly inclined portion of the cam grooves 284 in the cam plate. 283. The projecting edge 291 of the tucker first engages the vertically upstandin portion of the wrapper on the side which t ie tucker is approaching,'and folds said upstanding portion down on the top of the confection before or as the body of the tucker comes into contact with the confection. As the tucker advances, its body en# ages the body of the confection and pushes it before it into the space 219 between the upper and lower bridge plates 215 and 217 to the left of Fig. 8. This action causes the upper-bridge plateto fold the other upstanding margin of the wrapper down on top of the confection and on top of the other wrapper margin first folded down by the projecting edge 291. The tucker passes beyond and clear of the slot 262 in the lower bridge plate 215, and when it has done so, the roller 250il comes` into contact with the lswitch 271 at that end of the cam plates263 and is forcedl upward between said switch and the rounded end 267 of the'body 265 of said cam plate.4

This upward movement of the roller 250SL carries with it the support 246 and its stem 247 against'v the actionof the sprin 254, until the pivotal connection of the lin( 257 with said stem has passed above the pivotal connection of said link with the arm 256, whereupon the spring 254 acts upon the support and its stem in the opposite direction, and

serves to lift them upward to their original or normal position. At the same time, the cam groove 284,A acting on the roller 285, moves the slide 277 upward, and' brings the gripping fingers 279 back to their normal position, ready to grip the next confection. 1n the meantime, a second wrapper sheet anda second confection have been fed into position below the plunger 221, and said plunger, the support, and the gripping fingers are all in their normal position, the tucker being on the other side of their path, however.v The completion of the motion of the two slides in the direction now under consideration moves the plunger 221 downward by reason of the engagementof the roller231 with the inclined portion 229 of the cam groove 227 at the other end of the cam bar 224. The same series of operations just described again take place, the confection being carried downward by the depression ofthe support 2.46, and the lateral margins of the wrapper being left upstanding, while` the confection isv engagedby the gripping fingers 279. At this point, the slides again reverse their motion, moving once more in the direction indicated by the arrows in Fig. 8, and the plunger 221 rises, while the tucker 287 approaches the second confection from the other direction. The operation is the same as that already described, except that the other half of the cams 224, 263, 283 now controls the movements of the parts, and the tucker first folds lthe mar-4 gin of the wrapper to the left of Fig. 8, the other margin being folded as the tucker pushes the confection and wrapper from the path of the plunger to the right of Fi 8. A confection thus partially 4wrapped is s own to the extreme right of Fig. 8, with the tucker still pushing it forward and a proaching the limit of its movement in that irection.

In connection with the plunger it will be noted that, as in my rior patent, No; 833,785, the plunger is a h reason of the hollow or recess formed in its foot between the plates 241, so that, while the confection and wrapper are conveyed downward to the folding mechanism, the plunger does not press u 'on the confection, which latter is supporte from below.

The lower bridge plate 215 isprovided on each side with a lateralextension or arm 294, and the upper bridge plate 217 is simllarly provided on each side with an arm 295, lying above and extending somewhat berio ollow plunger by yond the arm 294. The construction is the same on each side 'of the lunger 221, so that 296, to receive the eentraltooth of the c0- 'operatin'g rake. f 'Each arm 225 has a downwardly extending support 297, to the lower end of which is pivoted one end of a rake arm 298. The construction which I prefer for this purpose is that shown, in which the sup ort 297 is provided with two lugs 299 at its ower end, to receive-between them the ends of the rake arm 298, which is connected thereto by a pivot bolt 300. The pivot bolt is extended on one side to form a support for a spring 301, coiled around said extension and connected thereto at one end, while its other end bears upon the top of the rake bar 298, to press the same downward. At its other or free end, the rake bar 298 carries a rake 302, comprising a central finger yor tooth'303, which extends downward through the slot 296 in the upper arm 295 and is normally hel-d against the upper surface of the lower arm 294 by the sprmg 301. Said 4rake also comprises lateral lingers or teeth- 304, which lie on each side of the arms 295 and 294 and therefore close the space between said arms at the sides thereof. At the inner end of the slot 296 there is located on top of the arm 295 a switch cam 305, pivoted to its Asupport at its inner end, as indica-ted at 306,

and held normally in the position shown by means of a spring 307. This switch cam has at its outer free end a lifting incline 308, which lies in the path of a pin or rejection 309, carried by the rake. Then t e rake is moving inward, the pin 309 ,rides up on this incline 303, and lifts the rake sol as to enable it to pass over and back of the wrapped confection which has ljust been pushed out on that side by the tucker 287. The switch cam is recessed or cut away near its pivot, as indicated at 310, so as to permit the rake to move downward back of the confection when the pin 309 reaches the recess 310. A fixed guide 311 is provided with an inclined cam surface which insures the downward' movement of the rake by reason of its engagement by the pin 309. As already stated, the shuttle is provided with vertical slots or grooves 293, which receive the rake fingers and permit them to pass downward back or inside of the confection lying in front of the shuttle. The switch cam 305 is provided, on the longitudinal face thereof adjacent to the slot 296, with a cam incline 312, which lies in the path of the pin 309, so that, during the outward movement of the rake, theswitch cam 305 is pushed to one side, against the pressure 'of the spring 307, to permit the rake to move outward without rising.

These rakes and their co erating mechan.

isms and `parts constitute conveying mechis actually conveying outward a confection while the other is returning for the next confection, and since one of the conveyers is always thus engaged in actual work, and the twisters cooperating therewith are simultaneously twisting, it will be seen that one set of these devices is always doing useful work. It will be further noted that the confection is held from turning and guided between the arms 294 and 295, which lie below and above the same while it is being drawn along by the fingers of the rake 302, and it will be understood that when the confection starts upon its outward movement, the untwisted ends of the wrapper project on each side of the arms 294 and 295, in position to be grasped by the twisters.

In connection with each rake 302 there are employed two tWisters, lying respectively on opposite sides of the arms 294 and 295, and

' carried by the corresponding ends of the two slides 207. Each slide 207 therefore carries two twisters, one at each of its ends, all four twisters moving in unison with the two slides. The construction of all the twisters is the same, and a description of one will therefore apply to all. Each twister comprises a support or bracket 31.3, mounted on the upper side of the slide 207, and having bearings 314, in which is mounted to rotate and slide longitudinally the twister sh aft 315.

This shaft is provided at its outer end with a head 316, in which is mounted an antifriction roller 31.7, having its aXis of rotation at right angles to the shaft 315. Said head also com-I prises a thrust collar 31.8 and bearing collar 319, which latter receives a non-rotating collar 320, which is held against the thrust collar 31S by spring pressure, so that the normal tendencjT of the shaft 315 is to move outward. To effect this spring pressure I prefer to employ an arm 321, having forked ends IOO IOS

322 to engage pins 323 on the collar320. The

arm 321 is pivoted on a standard-324, arising from the bracket 313, and a spring 325, coiled around saidstandard, acts onthe arm 321 to move its' free end normally outward. .Atjits other or inner end the shaft 315 is provided with a head 326, slotted transversely as indicated at 327, and in this slot there are'piv-v oted, at 328, the inner ends of the twisting fingers 329. (ln this inner end of the twister shaft there is mounted so as to rotate therewith and slide longitudinally thereon a scond head 330, constituting the controlling head for the twisting fingers, The head 330 is shouldered at 331 to engage thel head 326, and is slotted, as indicated at 332, for the passage of the twisting fingers 329.v On each side of each slot'332 are locatedflugs 333, which support a pin 334, said pin passing through a slot 335 in'the body of the corre- -mon rack bar.

- 349, located below the slide .207.

relative movement of said heads in the oppoextremity the desired finish after twisting.

The movements of the head 330 are preferably controlled in the following manner. The

'head 330 is reduced inl diameter at that end thereof nearest the bracket 313, as indicated at 338, and on the extremity of this reduced portion there is secured a collar 339, thereby forming between the body of the head and said collar a groove 340, in which is mounted a non-rotating collar 341. This collar has projecting therefrom pins 342, which are embraced by the forked ends 343 of a lever 344, pivoted on a standard 345, arising from the bracket 313. The lever 344 is centrally pivoted at 345, and has another arm or plunger, extending over the slide 207, which is provided with an aperture 346, while the lever 344 haseJ downwardly projecting .stud 347, which passes through said aperture and engages with a cam slot 348 in a 'fixed cam plate The cam slot 348 is so. shaped as to give the desired movement to the head 330 in the manner hereinafter described. 4 f l The twister shaft is rotated by means of a rack bar 350, each slide 207 having a contin-v uous rack Abar located above the same and provided with rack teeth on its under side at each end, so that the two twisters at the ends .of each slide are operated from a com- Each twister shaft 315 is provided with a gear 351, carried by a sleeve 352, splined on the shaft 315 and fitting between the bearings 314, so that the gear and shaft rotate in unison, while the'shaft is free to slide longitudinally with respect to the gear. E'ach rack bar 350 is provided at each end with a projection or stop 351, and has ivoted to each extremity a link 352, the ree end of which is slotted, as indicated at 353. These links connect the ends ofthe rack bar to tensioningarms 354, located at each end of each rack bar. Each arm 354 has at its free end a pin 355, engaging he slot 353, while its other end is pivoted on a standard 356, arising from the main frame of the machine. vA spring 357, coiled around the standard and engaging the arm 354, tends t0A move the same in the direction indicated by the arrow in Fig. 9, so that the tension arms 354 at the two ends of each rack bar tend to move in' opposite directions and maintain a pull or ltension upon said lrack bar. The movement of each arm is limited,however, many suitable manner, preferably by means of a stud 358, 'extending outward from the standard 356 through aslot 359 in the hub of the arm 354. The braeket 13 carries-a proi jection or stop 360, which cooperates with the stop 351 l at the corresponding end of the rack bar. Y

Assuming that the confection has been de-- livered. to the rake at either side of the niachine, ready for twisting, the twisters on that side of the machine will then be located near the central point of the wrapping mechanism,

separated as far as possible, and with the twisting fingers open, as indicated in full lines in Figs. 12 and 13. As the confection is carried outward by the rake, the slides 207,. moving in the same direction, carry the twister brackets along with them in their movement. By reason of the engagement of the stud 347 at one end of the lever 344 with the cam slot 348-of the fixed cani plate 349, the extremities 343 of the two levers 344 of the two twisters are caused to move to.- ward each other, thereby moving the. twister heads 330 toward each other and longitudinally with respect t0 the twister shafts 315 and their heads 326, which are still heldI againstlongitudinal movement by the spring controlled arms 321. This initial' movement of the heads 330 toward each other causes the twisting fingers to move into the position shown in dotted lines in Fig. 13, and to grasp between them the proviecting ends of the wrapper on each side'of a confection. During this period, the rack Vbars move -in unison with the twisters, and the twister shafts are therefore prevented from rotating, causing the twisting fingers to grip the paper properly and in such a way as to effectively hold the ends of the wrapper during the subsequent twisting operation. The rack bars 350 then become stationary, and the twister shafts are therefore caused to re- -volve, and to thereby4 twist the ends of the wrapper, .the confection being held against rotation between the arms 294 and 295. As the twisting operation proceeds, the wrapper becomes correspondingly shortened, and in order to prevent tearing of the wrapper as it shortens, the twisters are moved toward each other during the twisting operation. This movement is also effected by the cam slots 348, which, acting on the levers 344, cause their ends 343 to gradually approach each other. Since the heads 330 are 'now in 'engagement with the heads 326, the two heads will move in unison toward each other, sliding the twister shafts 315 toward each other in'their bearings against the action of `the spring-controlled arnis'321. This operation continues until the twisting is completed, and it will be understood that the twisters travel aloe-q with the confection and its conveying mechanism, the latter moving. the confection along, while the former maintain their position so as to twist the ends of the wrapperwhile the confection Land wrapper are traveling to 'the point of delivery.

IOC

.S2-(5 -from following the head 330 under'the iniiuence of the spring-controlled arm 321 and thereby preventing the. opening ot the twisting lingers, I provide a fixed contact cam 3G] at the side of the machine, with which the roller 317 at the end of the twister,

shaft i315 engages, thus preventing outward movement oi' the shaft 315. During this contact, it is necessary to prevent the shaft 315 from rotating, and to this end the tension arms 3.34 and their cooperating mechanisms are provided. When the twisting fingers open, the s to'p or projection 36() of each working twister head comes into contact with the io'ilwlating stop or projection 35].a on the rack bar 350, and the stops 351 are held. `against the stops 360 by means of the tension arms 354 at the 'further end of the rack bars, so that the relations of said rack bars and twister heads are fixed during the latter portion oithe movement of the twister heads. This ixity oi relation occurs when the shaft 315 is in the position shown, for instance, in Fig. 5, with the roller 31.7 lying in a horizontal plane, in which position it is maintained as it travels along in contact with the l-t will be seen that the rack bars movein unison with the twisters during the concluding portions ol their stroke in each direction, and, by reason of the slots 353 at the ends of the links 352a the same is true of the initial portion of the stroke in each direction, the rack bars always being held undertension at one end or the other. By reason of this tact, the twisters do not rotate during the initial portion of their outward travel, while the)l are engaged 1n closing their iingers upon the ends ot the wrapper, and said iingers alsoremain open during a considerable portion of their outward stroke at the end thereof, 1n order to permit free discharge of the confection and prevent said fingers from interfermg therewith. The completed wrapped coni'ection, after the twisters have been disengaged and withdrawn therefrom, is carried by the rake 302 outward past the end of the arms 294, fromavhich it falls into a suitable receptacle. The slides 207 then reverse the direction of' their movement and the twisters and rakes on the side of the machine just under consideration return to operate upon the confection next delivered to them, while the twisters and the rake on the .other side of the machine are conveying to the other discharge point the succeeding confection, and at the same time twisting the ends of its wrapper.

' It will be observed that by the provision of a double set o14 twisting mechanisms the capacity of the machine is very largely increased, and the slowness of the output, heretofore caused by the fact that the forming and folding mechanisms had to wait upon the slower action of the twisters, is entirely done away with, and the speed of the machine correspondingly enhanced. lt will be further observed that the two twisters which twist the o posite ends of a given wrapper rotate in t e same direction, so that the ends of the wrapper are twisted in the same direction. The direction of this twist is the same as the direction of the folding of the body oi the wrapper around the confection, so that the twisting tends to hold the wrapper more iirmly around the body, and. makes a tight package with comparativi-ly little overlap, and these results are not obtainable when the ends are twisted in o posite directions. Furthermore, the pac age thus formed can be readily and quickly opened by pulling the ends of the wrapper 1n.

opposite directions, as thistends to untwist 'the ends and open up the body of the wrap- It will be understood, oi` course, that although the wrapping mechanism -just described is designed primarily 'for use in wrapping con'fections, and more particularly for use in an organized machine for automatically forming confections from a batch of candy and delivering them wrapped for the market, said wrapping mechanism is also capable of use in other connections/ and for the purpose of wrapping articles and things other than confections.
